Cash flow forecasting software for accountants connects to a client's books - usually Xero or QuickBooks Online - and projects future cash movement so you can catch a shortfall before it happens. Fathom, Jirav, and Float are three of the most common picks, but they are not interchangeable: each is built for a different kind of engagement, and picking the wrong one means paying for features you will never open.
TL;DR
- Fathom is the strongest fit if you sell polished, client-facing advisory reports alongside three-way forecasts and manage several entities.
- Jirav is built for firms running full FP&A-style engagements - budgeting, headcount planning, driver-based models - not just a cash view.
- Float wins on simplicity: it auto-syncs with Xero or QuickBooks Online and shows a visual cash position with almost no setup.
What Is Cash Flow Forecasting Software for Accountants?
Cash flow forecasting software pulls actuals from a client's accounting system and projects inflows and outflows over a set horizon, usually weekly, monthly, or quarterly. Most of the tools worth using also build a three-way forecast that links the profit and loss statement, balance sheet, and cash flow statement, so changing one assumption updates all three automatically.
For a firm layering advisory work onto bookkeeping or tax, this is the difference between a defensible number a bank or client trusts and a spreadsheet guess that falls apart the moment someone asks a follow-up question. The features that actually matter when you are comparing options:
- Three-way, rolling forecasts that update automatically as new actuals come in.
- Scenario modeling so you can show a client best-case, worst-case, and base-case side by side.
- Native integrations with the accounting platforms your client base already runs on.
- Multi-entity consolidation if you manage groups, franchises, or holding structures.
- Driver-based planning that ties operational inputs - headcount, pricing, sales volume - to the cash outcome.
Fathom vs Jirav vs Float: What's the Real Difference?
Fathom leads on client-facing reporting and multi-entity consolidation, Jirav leads on full FP&A-style budgeting for firms selling fractional CFO work, and Float leads on fast, automated cash-position tracking with the lightest setup. None of the three is objectively best - the right one depends on what you are actually selling the client.
| Tool | Best For | Forecasting Depth | Key Integrations | Multi-Entity | Starting Price |
|---|---|---|---|---|---|
| Fathom | Advisory firms needing polished reports plus forecasts | Three-way (P&L, balance sheet, cash flow), rolling, linked scenarios | Xero, QuickBooks Online, MYOB | Yes, up to around 300 entities with consolidation | Quote-based, mid-tier |
| Jirav | Firms selling fractional CFO or FP&A services | Full budgeting, workforce and headcount planning, driver-based models | QuickBooks Online, Xero, NetSuite, Gusto | Yes, built for multi-department and multi-entity groups | Quote-based, premium tier |
| Float | Automated, visual cash-position tracking | Rolling cash view up to 3 years, drag-to-adjust dates, what-if scenarios | Xero, QuickBooks Online, FreeAgent | Effectively single-entity, single-currency | Around $50/month |
Fathom, one of the more established players in this space, says it is used by over 99,000 businesses worldwide as of December 2025, and its forecasting sits alongside a full reporting suite - which is why accounting firms often pick it as one platform instead of stitching together separate reporting and forecasting tools.
Which Cash Flow Tool Fits Your Firm's Client Mix?
The right tool depends on which service line the forecast supports, not which tool has the longest feature list. Match the tool to the engagement type below before you commit to a subscription.
- Advisory-heavy firms with several entities per client: Fathom's consolidation and presentation-ready reports do double duty as both the forecast and the deliverable you hand the client.
- Firms selling fractional CFO or FP&A retainers: Jirav's budgeting and headcount-planning depth matches what clients expect from a CFO-level engagement, not just a cash view.
- Firms adding light cash visibility to bookkeeping or tax clients: Float's auto-sync and visual timeline get a client a usable forecast in under an hour, without a modeling exercise.
- Firms still deciding whether to build a forecasting service line at all: our guide to practice management software for accountants is worth reading first, since where client work already lives affects how much setup a new forecasting tool actually takes.
What About Futrli, Calxa, or Dryrun?
Futrli, Calxa, and Dryrun cover the gaps that Fathom, Jirav, and Float leave open, mainly around short-term daily cash visibility, complex divisional structures, and project-based scenario work.
- Futrli (acquired by Sage in 2022) focuses on daily and weekly cash visibility, which suits SME clients that need granular, near-term tracking rather than a multi-year plan.
- Calxa handles complex multi-entity and divisional structures with forecasts running up to 10 years, but its output leans spreadsheet-style rather than client-presentation-ready.
- Dryrun is built around comparing several scenarios side by side, which fits agencies and project-based businesses better than steady, recurring-revenue clients.
- Cash Flow Frog builds an automatic forecast almost immediately from QuickBooks or Xero history, aimed at businesses under roughly $1M in revenue that want something usable today.
How Much Does Cash Flow Forecasting Software Cost in 2026?
Pricing splits into two tiers: lighter, automated tools that run around $30-$60 a month per client, and advisory-focused platforms priced on quote-based tiers that scale with entities and users.
Float starts around $50 a month and Cash Flow Frog starts around $29 a month, both with free trials so you can test before committing a client to it. Fathom and Jirav are both quote-based, positioned mid-to-premium tier, and pricing usually scales with the number of entities or clients you run through the platform rather than a flat per-firm fee. Confirm current pricing directly on each vendor's site before quoting a client, since these figures shift throughout the year.
How Do You Roll Out Cash Flow Forecasting Without Adding Hours to Your Close?
Roll out forecasting to one client segment at a time, connect one tool, and standardize a single template before you offer it firm-wide. Trying to run three forecasting tools across a small client base creates more reconciliation work than the forecasts save.
Start with the clients already asking about cash - the ones chasing a loan, a lease renewal, or a hiring decision. Connect their books, whether that's QuickBooks Online or Xero, build one forecast template you can reuse, and review it on the same cadence as your existing close so it does not become a separate deadline to track.

And if cash flow forecasting surfaces a bigger spend-management gap on the AP side, our comparison of Ramp vs Bill.com for accounting firms is a natural next read. Before you add any new software, it also helps to run through the operations audit questions that surface where the real time is going in your firm first.
How Does AI Help With Cash Flow Forecasting for Accountants?
An AI assistant does not replace the forecasting tool - it cuts the manual steps around feeding and explaining it. Applied to the exact tasks above, that looks like a few concrete wins:
- Drafting the variance commentary: instead of a preparer writing up why this month's cash position missed the forecast, an AI assistant can pull the variance data straight from the tool and draft the first version of the client-facing narrative, cutting review time to a quick edit rather than a blank page.
- Chasing missing assumptions: forecasts run on inputs like expected payment dates and outstanding invoices. An AI assistant can draft and send the follow-up emails asking clients or their customers for that missing data, instead of a bookkeeper doing it manually every month.
- Flagging mismatches before they reach the client: an AI assistant can cross-check the forecast's opening cash balance against the connected ledger in Xero or QuickBooks Online and flag any gap immediately, catching a sync error before it shows up in a client meeting.
- Summarizing scenarios in plain language: turning a best-case-versus-worst-case comparison into two or three sentences a client can actually act on, rather than a table they have to interpret themselves.
Which of these actually saves your firm hours depends on your current toolset, client mix, and how your team already handles month-end - which is exactly what a free CloseRadar operations audit maps out from a short questionnaire, naming the specific fit and the hours back before you commit to any new subscription.
